Abstract: 364,612. Calculatin g - apparatus. ACCOUNTING & TABULATING CORPORATION OF GREAT BRITAIN, Ltd., Aldwych House, Aldwych, London, and CAMPOS, F., 4, Rue DufrÚnoy, Paris. July 8, 1930, No. 11355. [Class 100 (iv).] Type-bar machines.-A machine for keeping accounts comprises a plurality of storing devices, selecting mechanism for segregating one of the account storing devices, means for reading the balance on the selected device, a setting mechanism for entering credit or debit items, and means for modifying the reading in accordance with the transaction so that the new balance is indicated and thereafter stored in the selected account device. Means are provided for totalling the transactions entered, for registering the credit and debit balances separately, and for recording the old balance, the transaction, and the new balance, as well as an identification number for the account and the date. The transmission gears which are associated with the adding wheels that read the accounts are mounted on nested sleeves 355, Figs. 59, 67, and 68, carrying at their other ends wheels 356 adapted to engage wheels 357 connected through other -nested sleeves 358 to wheels 359 adapted to mesh with teeth on type-racks 360. The booking wheels, which effect the entry of new items, gear with wheels 354 mounted on nested sleeves 354a provided with wheels 362 at their other ends in gear with wheels 363 on nested sleeves 364 which carry other wheels 365 normally in mesh with type-racks 360a. The numeral drums of the mechanism for selecting the accounts are also mounted on nested sleeves which pass through the hollow shaft of the booking wheels and carry wheels 366 in mesh with wheels 367 on nested sleeves 367a carrying wheels 368 in gear with other type-racks. Other data, such as code number of account sheet and date, may be printed. The code number is set up by manipulating levers attached to wheels 369, 369a on nested sleeves 372, the other ends of which carry wheels 373 gearing with wheels 374 on sleeves which pass through the sleeves 367a to wheels 375 engaging corresponding type-racks. Setting knobs 376 for the date are connected by wheels 377 to corresponding type-racks. The type members carried by these racks are movably mounted thereon and have vertical characters for credit items and oblique characters for debit items. Hammer-impression mechanism.-The main shafts 24, 148, Fig. 67, are connected by sprocket gearing to shafts 396, 400. The shaft 396, Fig. 74, carries cams 402, 403, 417, 419, and 419a co-operating respectively with a lever 389, with a key member 407, with a slidable member 411, and with the hammers 381 operating the strikers 380 to impress the type on racks 360 on the platen 360x. The shaft 400 carries cams 401, 410, 420, and 420a co-operating respectively with the key member 407 and with the slidable member 411, and with the hammers, 381a operating the strikers for the type on racks 360a. When the shaft 24 is rotated to read the amount standing on one of the account storing devices, and prior to the movement of the adding wheels which read the accounts, the cam 402 rocks the lever 389 and through the resilient connection 388, 392 and linkage 384 . . 387 raises the rod 383 to put the wheels 359 into engagement with the typeracks 360. After the setting movement the cam 419 co-operates with the tails 418 of the hammers 381 to effect an impression. During the above operation the key member 407, which is slidable over the shaft 390 of the lever 389, is operative to prevent the roller on the end 389a of the lever 389 entering a recess in the cam 402 since the shaft 400 is not rotated. The operation after a transaction has been entered on the booking wheels differs from the above described operation in as much as after a partial rotation of the shaft 24 the shaft 148 is given a complete rotation before the movement of the shaft 24 is completed. In consequence the cam 401 on the shaft 400 withdraws the key member 407 and permits the roller on the end of the lever 389 to enter the recess in the cam 402 and thereby rocks the lever 389 to disengage the wheels 359 from the type-racks. The cam 410 then operates the sliding member 411 which, by engagement with the pins 413 on pivoted scissor-like levers 414, effect the return to zero of the type-racks. At the end of the revolution of the shaft 400 the key member 407 is interposed between the end of the lever 389 and the hub of the cam 403 so as to re-engage the wheels 359 with the typeracks. Movement of the shafts 24, and 396, is then completed to set the type-racks to the new balance as modified by the item entered, and the cam 419a operates to effect an impression. Finally the wheels 359 are disengaged and the sliding member 411 moved by the cam 417 to reset the type-racks 360. The type-racks 360a are automatically reset by the return to zero of the booking wheels, the item entered on these wheels being printed during the rotation of the shaft 400 by the action of the cam 420 on the hammers 381a, Fig. 76. The cams 420a are effective when the total accumulated on the wheels 169 is to be transferred to a storing device and printed. The nature of the record, i.e. debit or credit, is identified by the kind of type selected. For this purpose the strikers 380 are tilted about a pin 428 by a link 425 having a pin 426 engaging the corresponding striker and connected to a bell crank 423, co-operating with ramps 422, 422a on the typeracks 360 of highest denomination. The links 425 are connected to arms 429 each carrying a lever 431 with a nose 431a co-operating with notches 434 in the type-rack. When a typerack is moved the nose 431a leaves the notch to free the link 425. If the rack movement is sufficient to permit the bell crank to move down the ramp 422 or 422a then the link moves to tilt the strikers. Disposed under each lever 431 is a lever 435 each with a projection which overlaps the lever of next lower denomination. Each lever carries a pivoted latch 437 with a recess engaging a projection 438 on the corresponding hammer 381, 381a, Figs. 74 and 76. When a type-rack moves from the zero position the lever 431 is rocked and the levers 435 with the latches 437 to the right are moved to free the hammers while the latches 437 are held in position to prevent the hammers operating the strikers. Duplicate printing in the operations above described is prevented by the return of the racks to their zero position. Platen - impression arrangements ; line-spacing mechanism.-The platen 360x, Figs. 83 and 84, is mounted on arms 470 operatively connected to a rock shaft 479 having arms 481, 482 cooperating with cams 483, 484 and cams 485, 486 respectively on the shafts 396, 400, so as to raise and lower the platen with respect to the type-carriers. The roll of paper on which the record is printed is led from a supply roll 488 over guide rollers and under a knife edge 492 to a feed roller 493. The feed roller is advanced by means of a ratchet and pawl 494, 495 operatively connected with an arm 499 pivoted on an axis member 500. The lever 499 carries arms 501, 502 co-operating with cams 503, 504, on the shafts 396, 400, the arms 501, 502 being adjustably mounted for the purpose of varying the step movement of the paper. A knife 507a pivoted on a shaft 508 is provided to facilitate tearing off the record-strip. Loose sheets with carbon papers are carried on a tray 513, Fig. 84, pivoted to an axis 515 so that when the tray is depressed on to the platform 491 the loose sheets can be passed under the platen, under a rail 516 carried by the platform, and over the knife edge 492. Ink-ribbon mechanism.-The ribbon is carried on spools 517, Figs. 84 and 85, disposed one on each side of a ratchet device 518 pivoted on a plate 519 operatively connected to a lever 522 pivoted on the shaft 500 and actuated by cams 523, 524, on the shafts 396, 400. A swinging plate 524 pivoted on an axis 524 carries two adjustably mounted projections 526, 527 which straddle a pin 528 on the ratchet device. One or other of the projections bearing against the ribbon causes a tilting of the plate 524 to throw the ratchet from one spool to the other. Specification 213,357, [Class 106 (i), Calculating &c.], is referred to.
